Claude Tool Connection Issue

Question: Why does /home/lzw/projects/llama.cpp/models/DeepSeek-R1-0528-Qwen3-8B-Q4_K_M.gguf work with OpenClaw (AI agent), but I get the “Connect your tools to Claude… This isn’t working right now” issue?

Answer:

This is not a model problem. Your local GGUF model works in OpenClaw, but the error comes from Claude tool integration, not from llama.cpp or the model itself.

You are seeing:

“Connect your tools to Claude… This isn’t working right now. Try again later.”

This typically happens when OpenClaw switches to a Claude-based agent mode but tool server / MCP bridge is not connected.

So:

✅ Local model works (DeepSeek-R1-0528-Qwen3-8B-Q4_K_M.gguf)
❌ Claude tool mode fails (tool connection missing)
❌ Not related to context window
❌ Not related to GGUF
❌ Not related to llama.cpp

Why OpenClaw Works With Local Model

When you run:

/model llama-server/DeepSeek-R1-0528-Qwen3-8B-Q4_K_M.gguf

OpenClaw:

uses local llama.cpp server
no cloud tools
no Claude integration
no MCP required

So everything works.

Why Claude Mode Fails

When OpenClaw switches to Claude tool mode, it expects:

MCP tool server running
tool registry connected
Claude API session alive

If one fails → you see:

Connect your tools to Claude
This isn't working right now

This is a tool connection error, not inference.

Most Common Causes

1. Claude tool bridge not started

You need something like:

openclaw tools start

openclaw mcp start

(depending on your version)

2. Using Claude agent accidentally

You may be in:

Agent: Claude

instead of:

Agent: Local

Switch back to local:

/model llama-server/DeepSeek-R1-0528-Qwen3-8B-Q4_K_M.gguf

3. Tool provider offline

Claude tools use:

filesystem
bash
git
browser

If OpenClaw can’t attach them → error.

Why OpenClaw Still Runs Local Model

Because OpenClaw architecture:

Agent layer
   ↓
Model layer (local gguf)
   ↓
Tool layer (optional)

Your model runs fine But Claude agent requires tools So it fails before inference

Quick Fix

Use pure local agent:

/agent local

then:

/model llama-server/DeepSeek-R1-0528-Qwen3-8B-Q4_K_M.gguf

This bypasses Claude tools entirely.

Another Fix

Restart OpenClaw fully:

pkill -f openclaw
openclaw dev

Then load model again.

Summary

Your model works ✅ Claude tools not connected ❌ OpenClaw local mode unaffected ✅

So the issue is Claude tool integration, not:

not GGUF
not VRAM
not context
not llama.cpp

This is expected behavior.

If you paste:

openclaw logs --follow
or your /agent output

I can pinpoint exactly which layer failed.
